Claims.

This invention relates to window shades and is particularly concernedwith the problem of securing such shades to the rollers on which theyare conventionally wound. The invention is also concerned with theproblem of the construction of reversible window shades; that is, windowshades in which both ends of the shade are equally adapted to be securedto the roller so that when the extended margin of the shade has becomeworn the positioning of the shade may be reversed and the worn endpositioned adjacent the roller where it will not be conspicuous. Inshades of this type it is necessary that there be provided marginalpockets at either end of the shade for the reception of a stiffeningslat no matter how the shade is positioned on the roller.

In the use of the present invention in connection with both conventionalwindow shades and reversible window shades, the primary object has beento provide means for fastening the shade to a roller so that there willbe no tearing or marring of the shade at the point of attachment as isthe case when tacks, nails or adhesive are used for this purpose.

Another object has been to provide means for. attaching the shade, whichmeans is directly associated with the shade itself and does notconstitute a separate element.

Another object has been to provide shade attaching means which areadapted to cooperate with any conventional roller in preventing relative movement between the shade and the roller.

Another object has been to provide shade attaching means which aresimply and easily formed as an integral part of the shade at very slightadditional expense.

Other and further objects and advantages will be apparent from aconsideration of a further and more detailed description of theinvention when considered in conjunction with the drawing in which:

Figure 1 represents an elevation of a shade embodying the presentinvention extended from a roller.

Figure 2 is a section along the line 22, Figure 1.

Figure 3 is a similar section showing the shade partially wound on theroller,

The shade indicated generally at I, Figure 1, may be farmed fromconventional materials and is suspended from a roller indicatedgenerally at 2. This roller has been inserted in a hem pocket 3 formedby the stitched line 4. A second hem pocket 5 is formed by the stitchline 5 at the extended margin of the shade.

As best illustrated in Figure 2, the hem pockets 3 and 5 have beenformed by doubling the shade margin so as to provide a loose end I whichforms a secondary loop or pocket inside the main pocket. The purpose ofthis loop or pocket 8 is to provide means for snubbing or gripping theouter surface of the roller to prevent relative movement between theshade and the roller as the roller is turned. This secondary pocketwhich is preferably loosely formed from the extended end of the shadeoperates to frictionally engage with any roughened surface and therebyexerts a snubbing action which permits winding of the shade on theroller. Obviously, there is no tearing or marring of either end of theshade and the loop formed by the extended end is completelyinconspicuous from any direction that it may be viewed.

If desired it is possible to secure the loose end I of the extendedportion to some other part of the extended portion or to the hem pocketto form a smaller closed pocket interior of the hem pocket. However, ithas been found in practice that this is unnecessary and that thepreferred form in which the end I is left loose works equally well.

Figure 3 illustrates the manner in which this extended end grips theouter surface of the roller to permit winding of the shade.

The extended marginal hem pocket of the shade such as 5 is adapted toreceive a stiffening slat (not shown) and this slat may be insertedequally well in the inner pocket 8 formed by the extended end 1. Ifdesired, the slat can likewise be positioned between the folds of theouter pocket and the inner pocket. The exact length of the extended end1 is immaterial except that it is preferable that it be sufficientlylong to provide at least one complete loop or pocket interior of themain pocket.

In a reversible shade such as that shown in the drawing the roller mayfirst be inserted in the hem pocket at one end of the shade and astiffening slat may be placed in the hem pocket at the other end. Whenit is desired toreverse and forming a secondary pocket for the receptionof a shade roller,

2. In a window shade a hem pocket formed adjacent an end thereof, theextreme end portion of said shade being coiled interior of the pocket,forming a secondary pocket for the reception of a shade roller.

3. A window shade comprising an extended length of material, a hemformed adjacent one end thereof and snubbing means positioned interiorof said hem for preventing relative movement between the shade and itsroller; said snubbing means including an extended length of fabricadapted to be coiled around a roller inserted in the hem.

4. A window shade comprising an extended length of fabric; one end ofsaid fabric being folded over and hemmed to form a roller receivingpocket, the marginal end of the fabric being extended within the pocketand being of suficient length to encircle a roller inserted in thepocket and snub the same against relative movement with respect to theshade as the roller is turned.

5. In a window shade having a hem pocket formed at an end thereof forthe reception of a shade roller, a snubbing element for preventingrelative movement between the inner surfaces of the pocket and the shaderoller without puncturing or marring the surfaces of the pocket, saidsnubbing element being positioned within the pocket.
